Larsen effect deletion processor with two channels, ultra-fast and fully automatic Klark Teknik DF1000

As the old adage says "we cannot judge a book on its cover", the true beauty of the DF1000 is hidden under its elegant aesthetic design and its friendly interface. Inside beats the heart of an automatic deletion processor of the Larsen effect with two channels, truly professional, developed by one of the main world manufacturers of high -end electronic signal processors. The Larsen effect detection algorithms of the DF1000, ultra -rapid and very precise, instantly find critical frequencies and apply up to 32 channel filters to eliminate the Larsen effect. Whether your application requires protection against the Larsen effect for speech, musical performance, or both, the DF1000 is the ideal solution. Whether conference rooms, concert halls or places of worship, any place equipped with a live sound system will benefit from the unprecedented performance and value of the DF1000.

Functionality
During the design of the DF1000, our engineers designed an entirely automatic Larsen suppressor which absolutely requires no configuration or any prior adjustment. Operating in real time, with a precision of detection of a sixth cycle, the DF1000 is an elegant "plug and play" solution to one of the most difficult problems of live sound: the Larsen. Once the DF1000 is installed online between your mixing console and your power amps, just turn it on, start the active button on the front panel and leave.

System improvement
The abolition of the Larsen effect is perhaps the main function of the DF1000, but the elimination of the Larsen effect also generates significant global performance of the system. By eliminating the annoying and potentially destructive Larsens, the output gain of your live sound system can be increased by 10 dB to provide the necessary room for maneuver.

Automatic DSP applies up to 32 filters per channel
Thanks to an ultra-fast larsen effect detection algorithm, the DF1000 automatically and "intelligently" locates up to 32 larsen effect frequencies per channel. The algorithm then regulates extremely narrow barcounts (up to 1/30th of octave) to reduce these frequencies while leaving the rest of the practically intact signal.

Operation in double mode
The DF1000 constitutes an exceptional eliminator of Larsen Stereo on the front (FOH). You can also use Canal 1 for FOH (Mono) and use Canal 2 on your monitors - for a single unit Larsen effect center.

Connections
The DF1000 offers all possible connectivity options: 2 symmetrical/asymmetrical inputs on XLR/TRS sockets combined on the line level and 3 -pin Euroblock connectors. The outputs are provided in the form of symmetrical XLR and Euroblock connectors.

Audio quality at the meeting
Whatever the type of audio presentation of which you are specialist, the DF1000 is your ticket for an area without Larsen. Easy to use and an affordable price, the DF1000 offers automatic and instant protection against the Larsen, regardless of the program material. Say goodbye to Larsen forever with the DF1000.
